2 Claims.

The present invention relates to new and useful improvements in machines for mixing molasses, syrup, and other viscous materials with grain or similar granular material to produceva stock food and the invention has for its primary object to provide means for heating the viscous material and maintaining the same in a heated condition for facilitating the mixing thereof with the grain or other stock food.

A further object is to provide a device of this character of simple and practical construction, which is eicient and reliable in performance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the l same is intended.

Other objects and advantages reside in the 4details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which: v Figure 1 is a side elevational view.

Figure 2 is a top plan view.

Figure 3 is a longitudinal sectional view through the heating cylinder.

Figure 4 is a fragmentary sectional view through the two-Way v'alve taken substantially on a line 4-4 of Fig. 1.

Figure 5 is a 4sectional view taken substantially' on a line 5-5 of Figure 2 and illustrating the pump, and

Figure 6 is a sectional view through the screen taken substantially on a line 6 6 of Figure 2.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates a storage tank having a manhole cover 6 in its top portion to provide access to the interior of the tank.

A supply pipe for the molasses or syrup, leading from a suitable source of supply, is designated at I and having a control valve 8 in the pipe, the pipe leading to the intake end of a. pump 9 driven by a shaft I0 by means of a pulley II from a suitable source of power, the shaft having a transmission mechanism I2 interposed therein of conventional construction for driving the pump at a selected speed.

A pipe I3 leads from the discharge end of the pump and extends into a substantially cylindrical heating chamber I4 where the pipe is formed into a coil I5. A branch pipe I6 leads from the feed pipe I3, the terminal of the pipe I6 with the pipe I3 having a two-Way valve Il therein to through the pipe I3 into the coil I5, or through the branch pipe I5 which is connected to the top of the storage tank 5.

From the coil I5 the pipevextends outwardly through the heating chamber, asshown at I8, the pipe I8 having branches I9 and 29, the branch I9 having a control valve 2I therein and communicates with the top ofthe storage tank 5 while the branch 20 communicates vwith a spray nozzle 22 extending through -the top of a cylindrical` conveyor 23, the branch 20 also having a control valve 24 therein.

Interposed in the pipe I8 is a meter 25, a pressure and temperature indicator 26 and a volume control valve 21, the meter, temperatureand pressure indicator and the volume control valve being of conventional construction.

The heating chamber I4 is closed at each end and provided with a longitudinally extending partition 28 forming separate compartments 29 and 30, the coil I5 being positioned in the compart-l ment 29. A pipe 3| connects with one end of the chamber I4 and is adapted for connection with the exhaust pipe of an internal combustion engine for feeding exhaust gases to the' heating chamber. Pivoted to one end of thepartition 28, adjacent the intake end, is a damper valve 32 adapted for swinging into a position for admitting the exhaust gases either into the chamber 29 or into the chamber 39, the damper valve having a control lever 33 positioned outwardly of the heating chamber. Extending from the rear end of the heating chamber I4 is a pipe 34 constituting a discharge pipe for the chamber 29, the pipe 34 leading into the storage tank 5 and communicating with a heating chamber 35 positioned in the bottom portionof the storage tank. The pipe 34 connects to one end of the heating chamber 35 and at the opposite end thereof is connected a return pipe 36 leading back to the chamber 304 0f the heating chamber I4. The chamber 30 of the heating chamber I4 is provided with an exhaust stack 3l extending through the top of the heating chamber.

One end of the conveyor 23 is provided with a feed hopper 38 into which the grain or other granular feed is adapted to be admitted into the conveyor. the conveyor having a feed screw 39 mounted therein on a shaft 40 having a pulley 4I at one end adapted to be driven by a belt 42 from a suitable source of power. At the discharge end of the conveyor is provided a trough 43.

The supply pipe 'l is also provided with a branch selectively control passage of the uid either .pi-pe 44 communicating with the bottom portion 4of the storage tank 5 and having a screen 45 positioned therein as Well as a cut-off valve 46.

The system thus provided will ,permit molasses or other liquid material to be fed directly to the mixer 23 from the main supply pipe 'I after passing through the heater I4, by closing Nalves 2| and 46 and opening valves 8 and 24, and oper- -ating valve l1 to opening the line leading to the coil I5 and closing the line I6, or the molasses may be fed to the mixer fromthe tank -5 by closing valve 8 and opening valve 46 rWithout disturbing the remaining valves.

Likewise the molasses may .by-pass the heater and enter the tank 5 directly from the pump by manipulating the two-way valve l1 to 'close the coil l5- and open the line I6, and the molasses may also be fed to the tank after passing through the heater and cut oi from the mixer by opening valve 2l and closing valve 24.

By operating the valves as indicated the supply to the mixer may be cut off or on without inl terrupting the operation of the pump.

It is believed the details of construction and manner of use of the `device will .be readily understood from the foregoing Without further detailed explanation.

Having described the invention what is claimed 1. A heating system for heating liquid for a mixing apparatus and comprising a liquid feed pipe leading from a source of supply to the mixing apparatus, an outer heating chamber surrounding a portion of the feedv pipe, a hot air supply pipe connected to the outer chamber, a storage tank, an inner heating chamber in the storage tank, an exhaust pipe leading from the outer chamber to the inner chamber, branch pipes leading from the liquid feed pipe to the storage tank in advance of the outer heating chamber and beyond the heating chamber, and valves for said pipes.

2. A heating system for liquids comprising a tank, -a heating chamber outwardly of the tank and having a plurality oaf compartments therein, means for selectively heating the compartments of' the chamber, a heating chamber in the tank, a discharge pipe leading from one compartment of the outer chamber to the inner chamber, a return pipe from the inner chamber leading to the other compartment of the outer chamber, a. liquid supply pipe extending through said one compartment and also connected to the tank, and

a valve in the pipe controlling passage of liquid to said compartment and to-said tank.
